00400	1. Someone (I forget who) has proposed to produce methane from
00500	manure.  According to him, each ton of manure produces from
00600	50 to 70 m↑3 methane.  I calculate that 60 m↑3 is 2117 ft↑3,
00700	and this is 90 lbs of methane, and about 20,000 BTU/lb can
00800	be obtained.  The 2x10↑9 tons of manure (according to some
00900	eco-source concerned with the disposal problem) would correspond
01000	to about 9x10↑6 tons of methane which would be about equivalent
01100	to the same tonnage of coal which is about 1/6 of U.S. production.
01200	Therefore, it would seem to be a worthwhile source.

01400		2. A second proposed source of methane is coal.  The bureau
01500	of mines calculate that there is about as much methane imbedded in
01600	coal as there is in the known natural gas reserves associated with
01700	oil.  T?ey spent $680,000 on a pilot plant that produces enough
01800	gas to heat 1000 homes but say that it should be cheaper now that
01900	they know how.  A.P. 30 Jan.
